  • Publication number: 20260004260
    Abstract: The present disclosure is directed to security settlement in financial markets and cryptographic currencies. Particular portions of the present disclosure are directed to a cryptographic currency protocol and to a cryptographic currency that includes a positional item. The cryptographic currency protocol supports a virtual wallet that, in various embodiments, is a security and cash account for storing and managing the cryptographic currency. Opening a transaction via the virtual wallet to transfer the cryptographic currency is a strong guarantee of the availability of funds in the virtual wallet because, e.g., funds are not transacted unless the commit phase is successful.

  • Publication number: 20240252781
    Abstract: An infant mattress assembly includes a box spring that is positionable on a bed frame for supporting the box spring above a floor. A mattress is attached to the box spring and an air chamber is integrated within the mattress. A plurality of vibration units is each attached to the mattress thereby facilitating the plurality of vibration units to vibrate air within the air chamber to soothe the child sleeping on the mattress. A heating element is integrated into the mattress for heating the mattress when the heating element is turned on to warm the child. A control unit is integrated into the box spring and the control unit is in remote communication with a personal electronic device thereby facilitating the personal electronic device to remotely control the vibration and the heating element.

  • Publication number: 20240079955
    Abstract: A switched-capacitor DC-DC converter circuit may convert an input voltage into a desired output voltage level. A comparator may compare a desired voltage level to a divided version of the output voltage. A fully digital control circuit comprising a frequency divider circuit, a counter circuit, a digital control logic circuit and a gain selection circuit may generate a gain value, and a phase generator may convert the gain value into clock phase signals and control settings to control a switch array to select capacitors to produce a desired output voltage.

  • Publication number: 20230143159
    Abstract: A smart obturator assembly includes a hub forming a central passage. The hub is configured to couple to a proximal end of a device that forms a lumen such that the central passage is in fluid communication with the lumen. A collar on the hub includes electronic circuitry in signal communication with remote reception circuitry. An obturator is movably positionable within the lumen. The obturator is movable within the lumen between a first position and a second position. The obturator includes a distal end and a sensor at the distal end. The sensor is configured to sense an environmental characteristic within a patient’s blood stream, generate a signal representative of the environmental characteristic, and transmit the signal to the electronic circuitry. The electronic circuitry is configured to receive the signal and transmit the signal to the remote reception circuitry.

  • Patent number: 11385616
    Abstract: An actuator of a process control device continuously monitors actuator force and records high force values at each position point by continuously executing a routine in a processor of the actuator. The routine includes receiving from a position sensor a current position value indicating a position of a valve element in the valve, and from a force sensor a current force value indicating a force applied by the actuator. The routine also includes retrieving, from a memory device coupled to the processor, a previous force value measured at the current position, and comparing the current force values for the current position with the previous force value for the current position. If the current force value for the current position exceeds the previous force value for the current position, the routine replaces the previous force value for the current position with the current force value for the current position in memory.

  • Patent number: 11185259
    Abstract: An obturator assembly includes an obturator at least partially positionable within a lumen of a device. The obturator has a distal end with a tip portion and an opposing proximal end. A sensor assembly is at the tip portion. The sensor assembly is configured to sense one or more environmental characteristics and to generate one or more signals representative of the one or more environmental characteristics. A hub is operatively coupled to the obturator. The hub is also operatively coupled to electronic circuitry that is coupled in signal communication with the sensor assembly. In certain embodiments, the electronic circuitry is configured to receive the one or more signals from the sensor assembly and transmit the one or more signals to remote reception circuitry and/or display a datum representative of the one or more environmental characteristics on a display of the hub.
